The Marches, Shropshire: With the glory of summertime comes hayfever, which we are only making worse

Purple and silver: the solstice grass flowers. This is the first year that the whole five acres of Brogyntyn park has been left uncut, and Oswestry has designated it a wildflower meadow. The transformation is enchanting. The many buttercups, ox-eye daisies and few orchids have privilege, but the grasses are the liberated proletariat that have never realised its full potential before.

Common grass names have an earthy poetry: fescue, false oat, foxtail, fog, bent, brome, couch, cocks foot, timothy, rye, sweet vernal, squitch. For a couple of days it stops raining and warms up a bit. When the sun comes out, so does the pollen. VH, a red sign on the weather map, announces a very high pollen count (more than 150 grains per cubic metre of air). About half of the people in the UK report hayfever symptoms – allergic rhinitis. It can mean itchy eyes, runny noses, sore throats and sneezes for millions, but for some the reaction can be deadly serious. Dogs, cats and horses are also affected, as if sacrificing an immune system is a trade-off for domestication.
